Description
Congratulations on your purchase of the Prio® Expert R.O. ltration system! With proper
installation and maintenance, it will provide you with high quality drinking water for many
years.
This R.O. system removes odor and most harmful substances such as heavy metal ions and
total dissolved solids from tap water making it tasty, fresh and vital.
This Reverse Osmosis ltration system consists of two units: the sophisticated pump box
with auto-ush control valve and powerful booster pump and the R.O. ltration unit with
high-production R.O. membrane. Together, they provide direct ow capability of water ltra-
tion in real time, eliminating the need of a water tank usually found on conventional systems.
Please familiarize yourself with the general concept behind the product and main modes of
operation.
Key Features:
■
Clean and safe drinking water right in your home. No need to transport and dispose of
bottled water any more.
■
Factory-preinstalled lters and membrane for faster and easier setup.
■
Filters and membrane quick-change housings for easy regular maintenance.
■
Compact and beautiful design.
■
Automatic ush valve: for peak performance and healthier membrane. 18 seconds of
powerful ush at the end of each water ltration cycle prevent the scale and debris build-
up on the membrane outer surface.
■
Powerful booster pump increases pressure to radically improve the performance and ef-
fectiveness of the R.O. unit in all three key areas: increases ltered water ow (production
rate), increases rejection rate (improves water purication quality), increases recovery
rate (decreases amount of waste water).
■
Prolongs the membrane and pre-lter(s) service life due to increased recovery rate.
■
Fully automatic operation of the pump box unit: just open the faucet and get clean water
instantly; automatic shut o and ush.
■
LED indicators: easily understand what the state of your R.O. unit is.
■
Split, exible installation possible where needed: install the pump box up to 50 feet away
from the R.O. unit itself. Useful for the situations like lack of space or lack of electrical
outlet under the sink, or moving the unit to more appropriate place.
■
Idling protection: if you forget to shut o the ltered water faucet for a long time the pump
will shut down automatically for you.
■
Full separation of electrical components from the membrane and lters of the main R.O.
unit makes the regular servicing of your R.O. machine both easy and safe: no need to
worry about electrical valves and wires while changing your water lters or membrane.
■
Quick ttings for easy tube connections and change of lters.

Direct Flow R.O. Systems Benets:
Powerful booster pump and high-production R.O. membrane make it possible to build a high-
end direct ow R.O. machine that oers high performance and water quality.
■
Freshness of water ltered in real time. No more stale water from a tank.
■
Virtually unlimited ltered water production. While conventional systems with tanks are
limited by the tank capacity, and require prolonged timeouts to rell the tank, a direct ow
system is limited by the membrane ltration rate only.
■
Instant and sustained ltered water ow. It doesn’t depend on how full the tank is.
■
Space-saving, compact installation since tank is not needed.
■
Better water purication quality due to improved contaminant rejection rate.
■
Typically, up to three times less water is wasted per gallon of ltered water, compared to
the conventional tank and water storage systems, this is due to the much higher eciency
(recovery) rate. Saves you money and Planet Earth’s water resources!
■
Lower cost of ownership due to prolonged service life of pre-lters and membrane, which
is in turn a result of higher eciency rate: less water is treated overall by pre-lters and
the membrane for each gallon of permeate produced. This saves the capacity of pre-lters
and ensures either less frequent change necessity or better purication.
■
Less number of components leads to better reliability.
How It Works:
The MOD600 direct ow reverse osmosis system is a multi-stage automatic ltration machine.
The system consists of the two main units – the pump box and the R.O. unit – which are con-
nected with three tubes. This inter-unit connection distance is up to 50 . Water supply is done
through the inlet valve, ltered water is delivered through the faucet, and waste water is drained
through the drain saddle. Deta led connection scheme is shown on the following charts.
4
Page 5
Usually, both units – the pump box and the R.O. unit – are placed under the sink (such as in your
kitchen) and the ltered water facet is mounted on the sink deck near your normal water tap.
Aer installation, you will get clean water by simply opening the ltered water faucet. The
pump will turn on automatically and will produce ltered water in real time until you shut o
the faucet. At the end of each water production cycle the membrane will be ushed for 18
seconds, and then the system will shut o automatically.
LED Indicators (on the Pump Box Unit):
■
No Source: there is no water in the inlet line or it’s pressure
is less than 7.25 psi (0.05 MPa). Make sure the inlet tube is
connected and not kinked, and the water inlet valve is open.
■
Working: the pump is working and connected R.O. unit is
producing the ltered water for you while ltered water fau-
cet is open. No action is required.
■
Ready: ltered water faucet is shut. The pump is o. No ac-
tion is required.
■
Flush: 18 s membrane ush is going. No action is required.
■
Reset: idling protection was triggered. The pump is o. To
restore normal operation power cycle the pump box unit.
Pressure Switches:
The pump box unit is equipped with low and high pressure switches. The low pressure switch
shuts o the pump when there is no inlet water or its pressure is too low. The high pressure
switch shuts o the pump when the ltered water faucet is turned o.
Pump:
The pump box unit is equipped with a low voltage booster pump powered by the included
transformer for safe operation.
Inlet Valve:
An adapter ball valve is included to be installed into the cold water supply line to feed water
to the pump box inlet.
Faucet:
Designer faucet for ltered water is included and usually mounted on the sink deck or countertop for dispensing the clean, ltered water from the ltered water outlet of the main R.O. unit.
Drain Saddle:
Fits a standard 1.5” diameter drain pipe to drain the waste water from the drain outlet of the
pump box.
Pre-Filters:
The main R.O. unit has two pre-lters: sediment pre-lter on the rst stage and activated
carbon pre-lter on the second stage. They provide initial ltration of the water and protect
the following thin lm composite R.O. membrane from dirt and aggressive chemicals such as
chlorine oen found in tap water.
5
Page 6
R.O. Membrane:
The third and main stage of the ltration is high-production R.O. membrane. It is “semi-permeable”, which means that it allows water to pass through but prevents dissolved particles
from passing through. It splits the feed water into two streams: clean water goes to the
post-lter and then onto the faucet. Waste water with rejected particles goes down the drain.
Post-Filter:
Last stage of ltration is an activated carbon post-lter and/or remineralization for ne con-
ditioning and keeping the extra freshness of your water.

Installation
Notes:
1. Shut o the cold water supply under the sink or the location where the system will be
installed. If the existing valve is inoperable, the water supply to the house must be shut
o. Then, relieve the water pressure by opening the cold water tap. Do not connect the
system to hot water source.
2. Depending on your plumbing system and sink/countertop type you may need to use tools
like variable speed drill, drill bits, screw driver, wrench, etc. You may want to ask a profes-
sional service provider such as certied plumber to install the inlet valve adapter, faucet,
and drain saddle to assure a trouble-free setup.
3. During installation you will need to cut the supplied ¼” tubing into segments as needed.
Use your utility knife for that or similar tool. See the following charts to determine the
connection scheme and length of hoses necessary. You may need to purchase extra tubing
for far-reaching split or other corner case installations.
4. Do not connect the pump box unit to the electrical supply until the setup is completed.
5. With initial operation, check for leaks. If a leak is observed, verify that the tubing is pushed
into the quick tting far enough to seal the tubing against the O-ring and that the tubing
was cut at 90

Initial Washing:
Aer installation it is recommended to perform the initial washing of the system. For this:
■
open cold water
supply valve;
■
open the inlet
valve;
■
open the ltered
water faucet;
■
plug the pump
box unit’s power
cord into the
electrical outlet;
2 min
■
wait for water to arrive at the faucet (it
may take a while, water foam and air may
be going out of the system);
■
wait for 2 minutes for more or less steady
water ow from the faucet and shut o
the faucet;
■
wait for auto ush to complete (18 s);
repeat
2 min
5-10
times
■
repeat the cycle “open the ltered water faucet – wait for 2 minutes – shut o the ltered
water faucet – wait for auto ush to complete” 5-10 times;
■
aer you nished with previous step shut o the faucet, and your system is ready for use.
Please note that aer initial installation or changing the lters or membrane, air contained
in the new dry system or lter may go out sometimes producing foamy, white ltered water.
Water may look white due to tiny air bubbles in it. If you leave the water to stand for few minutes all bubbles will surface and eliminate. Such aerated water is clean and safe. Gradually
over the coming days all air inside your system will nd its way out. To make this process
faster you may repeat the initial washing procedure until you’re pleased with the result. Also
note that if for some reason the water supply contains a lot of dispersed air, your R.O. system
may start producing aerated water again. The system’s internal pipes and components never
take air from outside as they are completely air and water sealed and leak-free.
12
Page 13
Regular Use
To get clean water just open the ltered water faucet. The pump will turn on automatically and will
produce the ltered water ow in real time until you shut o the faucet. At the end of each water
production cycle the membrane will be ushed, and then the system will shut o automatically.
Please note that R.O. membrane needs up to 50 hours of active operation before reaching
peak performance in terms of water ow, recovery and rejection rates.
For your safety and peace of mind please unplug the pump box unit from the electrical out-
let and shut o the inlet valve before servicing your R.O. system such as changing lters or
membrane, or during vacations.
Tips:
■
You may install the optional union tee tting to the tubing line prior to the ltered water
faucet to get another line of clean water going to the other point-of-use (such as a sink in
a bathroom or ice maker in your fridge).
■
Operating the system using soened feed water greatly reduces the chances of membrane
failure and prolongs lters and membrane service life.
Changing Filters and Membrane
This R.O. system contains the replaceable components critical to the eciency of the system.
Replacement of a component should be with one of identical specications, as dened by the
manufacturer, to assure the same eciency and contaminant reduction performance.
To reduce the risk of water leakage or ooding, and to ensure optimal R.O. system performance:
■
Change the disposable pre-lters every 6 months or sooner if you observe a noticeable
reduction in water ow rate.
■
Change the disposable post-lter every 12 months or sooner if you observe a noticeable
reduction in water ow rate.
■
Change the disposable R.O. membrane every 36 months or sooner if you observe a notice-
able reduction in water ow rate.
Failure to replace the disposable lters & membrane at recommended intervals may lead to reduced system performance and cracks in the lter housings, causing water leakage or ooding.
Please note the capacity of the lters and membrane is limited. Their service life depends on
the degree of contamination of the water supply and system usage. All terms apply to normal
household use. Actual performance may vary. You may need to change lters or the membrane sooner than indicated if you notice chlorine or other tastes or smells, etc. Manufacturer
recommends a TDS test every six months.
Replacement Filters:
■
K871 (sediment pre-lter)
■
K870 (activated carbon pre-lter)
■
K858 or K856 (high-production R.O.
membrane)
■
K880 (activated carbon post-lter and
conditioner)
Optional post-lters which can also be used
instead of K880:
■
K875 (granular activated carbon post-lter)
■
K873 (granular activated carbon with
schungite natural mineral post-lter)
■
K870 carbon block pre-lter may also be
used as a post-lter.
To prevent leakage or cracks and ensure the safety of operation and top performance do not
disassemble the lters or try to regenerate them.
